A new fingerprint image representation which captures both the local features such as minutiae and the global features such as overall ridge structure is presented. The basic tool is a set of oriented band pass filters which are parametrized by three parameters. We relate quantitative filter responses to the structural characteristics of the fingerprint ridges.
